Antioxidant availability trades off with warning signals and toxin sequestration in the large milkweed bug (Oncopeltus fasciatus)
Sign Up to like & getrecommendations! Published in 2023 at "Ecology and Evolution"
DOI: 10.1002/ece3.9971
Abstract: Abstract In some aposematic species the conspicuousness of an individual's warning signal and the concentration of its chemical defense are positively correlated. Several mechanisms have been proposed to explain this phenomenon, including resource allocation trade‐offs… read more here.

Spatial analysis of early-warning signals for a North Atlantic climate transition in a coupled GCM
Sign Up to like & getrecommendations! Published in 2018 at "Climate Dynamics"
DOI: 10.1007/s00382-018-4567-7
Abstract: The climate system can potentially switch from one stable state to another. The closer a system is to a bifurcation point (i.e., ‘tipping point’), the more likely it is that even small perturbations can force… read more here.

DOI: 10.1016/j.ecolmodel.2018.11.003
Abstract: Infectious disease outbreaks in plants threaten ecosystems, agricultural crops and food trade. Currently, several fungal diseases are affecting forests worldwide, posing a major risk to tree species, habitats and consequently ecosystem decay. Prediction and control… read more here.

Early warning signals noticed, but management doesn't act adequately or not at all: a brief analysis and direction of possible improvement
Sign Up to like & getrecommendations! Published in 2020 at "Journal of Loss Prevention in the Process Industries"
DOI: 10.1016/j.jlp.2020.104272
Abstract: History has taught us that quite disastrous events with much human loss, injuries and asset damage could have been prevented or at least mitigated, if top management had recognized early warning signals in some form… read more here.

DOI: 10.1016/j.mex.2020.100920
Abstract: We present results of attempts to expand and enhance the predictive power of Early Warning Signals (EWS) for Critical Transitions (Scheffer et al. 2009) through the deployment of a Long-Short-Term-Memory (LSTM) Neural Network on agent-based… read more here.

DOI: 10.1016/j.trd.2020.102502
Abstract: Abstract Trains on railways collide with and kill wildlife, incurring economic costs for railway operators and impacting species of conservation concern. We proposed to address this problem with train-triggered warning signals, consisting of flashing lights… read more here.

Eigenvalues of the covariance matrix as early warning signals for critical transitions in ecological systems
Sign Up to like & getrecommendations! Published in 2019 at "Scientific Reports"
DOI: 10.1038/s41598-019-38961-5
Abstract: Many ecological systems are subject critical transitions, which are abrupt changes to contrasting states triggered by small changes in some key component of the system. Temporal early warning signals such as the variance of a… read more here.

DOI: 10.1073/pnas.1901872116
Abstract: Significance With our comprehensive set of field (model survival), laboratory (controlled learning, palatability, toxin analysis), and molecular data, we provide evidence that polymorphism can persist in an aposematic population, despite expectations of positive frequency-dependent selection.… read more here.

DOI: 10.1073/pnas.2106140118
Abstract: Significance Early warning signals (EWS) of tipping points are vital to anticipate system collapse or other sudden shifts. However, existing generic early warning indicators designed to work across all systems do not provide information on… read more here.
